Now would be a bad time to sell them. Why not do a temporary loan to your local Library for others to look at and enjoy. A lot of Seniors have been there/done that, and use the Library on a regular basis. I have scanned and posted cards from the Tashmoo steamer, and Polar bears here before. Worst case scenario - all Dyesr's donate cards as a collective to the Burton or Wayne State archives for just the pride of doing so.
